Lab & R&D Space Costs on the Peninsula (2026)
Lab occupancy cost combines base rent, operating expenses, specialized utilities, fit-out, equipment, and time before the facility can operate. Compare a second-generation lab with a shell using the same technical scope. A regional asking-rent average is context, not a quote for an available small lab.

Use the right market benchmark
These are different datasets, not interchangeable estimates for one building. R&D includes space that may not meet a wet-lab requirement. Small furnished labs, shell premises, and specialized manufacturing facilities can also price differently. Confirm the exact suite, lease structure, operating-expense estimate, and available systems.
| Report and period | Reported asking rent | What it describes |
|---|---|---|
| CBRE, Q2 2026 | $5.46/SF/month NNN | Bay Area life sciences overall average asking rate. |
| Kidder Mathews, Q2 2026 | $6.62/SF/month NNN | South San Francisco R&D average direct asking rate. |
| Kidder Mathews, Q2 2026 | $5.50/SF/month FSG | Peninsula office average; a different property category and expense basis. |

Turn a rate into a monthly budget
Illustrative calculation: 5,000 rentable square feet at CBRE’s $5.46 monthly NNN benchmark produces $27,300/mo in computed base rent. It excludes NNN charges, utilities, services, fit-out, and equipment. This is arithmetic using a regional average, not an available-space quote.
Obtain the landlord’s current expense budget, reconciliation history, and responsibility schedule. Ask who pays for process cooling, exhaust, gas systems, backup power, waste handling, and maintenance. A space with reusable systems can still require recertification, repair, or changes for your process.
Fit-out cost and landlord allowance are different numbers
Cushman & Wakefield’s 2026 life sciences guide, published December 16, 2025, reports an average fit-out cost of $741/SF across its study. That pooled figure covers different facility types and markets; it is not a South SF small-lab estimate. Use the guide to scope the conversation, then obtain a facility-specific design and contractor budget.
For a dated financing reference, Cushman & Wakefield’s Q1 2025 leasing analysis described Bay Area life-sciences TI packages of $200–$250/SF. That is historical landlord-contribution context, not a current offer or a construction-cost range. Allowance eligibility, lease length, tenant credit, and reimbursement timing all matter.
Build separate low, expected, and high project budgets from actual bids. Do not create a supposedly local fit-out range by combining unrelated national laboratory averages. State the scope, usable versus rentable area, included equipment, contingency, and quote date for each estimate.

Compare second-generation lab, spec lab, and shell
Ask for a room-by-room equipment and systems inventory. Confirm which items remain, which are warranted, which are leased from another party, and who removes or reinstates them at exit. A previous biotech occupant is evidence to investigate, not confirmation that the next process is approved.
| Option | Potential advantage | What can undo it |
|---|---|---|
| Existing lab | Reuse a compatible layout and systems | Equipment ownership, deferred maintenance, decommissioning, or an incompatible process. |
| Spec lab | A defined landlord delivery package | Missing equipment, utility allocations, commissioning, or a delivery date outside your plan. |
| Shell | Design around the process | Capital required before reimbursement, permit dependencies, equipment lead times, and restoration. |
Make the occupancy schedule a set of gates
The schedule must come from the actual design and approval path. No Onshore lab-deal completion dataset is published here, so these gates are not presented as measured client timelines. South SF publishes guidance on commercial work requiring permits; discuss the actual scope with its Building Division.
- Technical diligence: process description, design brief, utility capacity, environmental and materials review.
- Commercial agreement: delivery condition, allowance, access, rent commencement, and obligations if work is delayed.
- Design and approvals: building and trade permits plus approvals applicable to the operation.
- Construction and commissioning: installation, testing, inspections, and acceptance.
- Operational readiness: equipment qualification, staff, services, and the approvals needed to begin work.
Start with a process brief
Tell Sam whether you need wet lab, dry lab, engineering benches, testing, or pilot production. Add the materials, equipment, utility demand, team size, and operating date. A general industrial listing can be useful for some hardware R&D, but it should not be relabeled as a permitted wet lab without evidence.
For each candidate, compare the monthly occupancy budget, tenant cash before reimbursement, remaining work, and the earliest credible operating date. Keep an alternative ready until the most consequential technical questions are resolved.
Common questions
Is $5.46/SF/month the all-in cost of a Bay Area lab?
No. CBRE’s Q2 2026 figure is an overall life-sciences asking-rent average on a NNN basis. Expenses, utilities, fit-out, equipment, and other costs are additional or must be confirmed.
Is an R&D listing necessarily a wet lab?
No. Confirm the actual improvements, systems, permitted operation, and equipment. R&D is broader than a ready-to-use wet laboratory.
Does a TI allowance remove upfront cash needs?
Not necessarily. Work may have to be funded before reimbursement, and some costs may be ineligible. Read the work letter and payment conditions.
